Using the slope concept, it is found that the angle of elevation to the top of the bridges is of 57.7º.
<h3>What is a slope?</h3>The slope is given by the <u>vertical change divided by the horizontal change</u>.
It's also the tangent of the angle of depression.
In this problem:
- The horizontal change is of 60 m.
- The vertical change is of 100 - 5 = 95 m.
Hence:
The angle of elevation to the top of the bridges is of 57.7º.

Answer:
x = 20
Step-by-step explanation:
given f(x) = , we have to solve
= 4
Square both sides
()² = 4²
x - 4 = 16 ( add 4 to both sides )
x = 20
As a check
=
= 4 ← correct
